If you go with a cluster, then this raises the question of who needs
to be able to run alone.  If each side needs to be able to run without
the presence of the other then either:

a)  each needs a vote and there needs to be a third node that also has
    a vote in case one of the main systems go down.  Two out of three
    must be up at all times.

OR
b)  if one system goes down, then reboot the remaining system from
    another root that is not clustered.

Other things are possible, depending on your requirements.
